WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 335,567, dated February9, 1886.

Application filed August 20, 1885. Serial No. iT-L855.

To (LZZ whom it may concern:

Be it known that I, GEORGE CROMPTON, of \Vorcester, countyof \Vorcester,and State of Massachusetts, have invented an Improvement in W'ovenFabrics, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to produce a cheap, strong, firm, anddurable double-faced carpet fabric, wherein the figure at each side thefabric is derived from face-warps carried, preferably, by twoharness-frames, the said face-warps appearing at one and then at theother side of the fabric for one or more picks. The face-warps havecooperating with them a binder-warp, preferably one thread of binderwarp to every two or more threads of face warp. The said face-warps andbinder-warps are caught and held together by stuffer or cord weft andbinder-weft. The binder-weft at alternate picks passes above all thefacewarps and then below all the face-warps, the binder-weft being tiedto the upper and then to the lower side of the face -warp by thebindcrwarp, two picks of binder-weft and two picks of staffer or cordweft being put in in succession, the binder-warp being lifted into theupper half of the shed between the insertion of the first and secondshots of stuffer or cord weft, the binder-warp thus splitting thestaffer or cord weft, the crossing of the warp an d weft being such,substantially as described, as to enable the two shots of staffer orcord weft when beat up into the shed to lie one substantially over theother, forming ribs substantially opposite each other at opposite facesof the fabric, instead of leaving the rib on one side opposite the spaceor groove at the other side and in line with the binder-weft, thebinder-weft occupying similar positions opposite each other and betweenthe cord-weft when heat into the shed, the fabric thus made show ingpermanently at each side loops of face warp filled with a stuffer orcord weft, the large and more expensive face-warp being tied downclosely at each side the large stuffer or cord weft, making astrong,firm,and durable fabric.

My invention consists, essentially, in a double-faced fabric madesubstantially as will be hereinafter described, and composed of face-(No Specimens.)

warps and binderuvarps, the warps from the two surfaces beingalternated, that from the lower surface passing to the upper surface,and vice versa, the sai d face-warps receiving in each shed made betweenthem two shots ofstuffer or cord weft, and being tied together about thesaid stuifer orcord weft by fine binder-weft, the stuffer or cord weftbeing split by the binder warp in each shed made in the face-warps.

Figure 1 represents a longitudinal section of a piece of fabricembodying my invention; Fig. 2, a diagram representing the arrange mentof the warp and weft threads in the fabric; Fig. 3, a longitudinalsection of the fabric as it will appear when beat up closely.

The threads shown in Figs. 1 and 2 are separated to avoid confusion; butin the actual fabric the said threads will all be beat closely togetherby the reed, and substantially as in Fig. 3.

To produce the carpet, I make use of an ordinary twoshuttle loom, wellknown in the art to which this invention relates, with the addition ofinstrurnentalities for controlling the binder-warps, and also forraising and lowering at stated periods, as hereinafterset forth, all ofthe face or body warps.

For the binder-warps an independent set of harness is provided, the samebeing operated through any of the well-known intermediaries used forlike purposes from a cam on the picker-shaft.

The sheds for the binder-weft are formed by the binder-warps on the onehand and by all the-face or body warps on the other hand.

The face-warpsA A, preferably of wool and of different colors, and. dyedor printed according to the colors and patterns it is desired the carpetshall show, will be manipulated, preferably, by two harness -frames ofusual construction, so as to split the face-warps at suitable intervalsto form sheds for the introduction of the stuffer or cord weft B B,carried by a shuttle, the face-warp threads uppermost or at one side ofthe fabric remaining at that side of the fabric for as many picks asdesired, and then being carried to the other side of the fabric.

The binder-warps b, of fine strong thread, carried by one harness-frame,are distributed at suitable intervals between the face-warps,

and are made to appear at oneend at the other side or face of the fabricbetween each two shots of stuffer or cord weft.

The binder-weft w will be carried by a suitable shuttle.

Starting from the line D, Fig. 1, the face warps are all lifted and thebinder-warps left down, thus forming a shed between all the face-warpand the binder-warp to receive a shot of binder-weft 20, then a part-saysubstantially one-half-of the face-warp will be lowered by theharness,which, with the binderwarp then down, forms a shed for thereception of the pick No. 1 of stuffer or cord weft B.' Then thebinder-warp b is lifted above the lower half of the face-warp thenremaining down, and a second shot, 2, of stuffer or cord weft, B, isinserted in the shed formed. Thenmitted to descend, and a second shot(marked 2) of binder-weft w is thrown, and this operation is repeateduntil such time as it is desired that the face-warp uppermost in thelast shed to receive the stuffer or cord weft lfoe made to appear at theopposite side of the "abric.

When it is desired to make the warp at one face of the fabric show forone or more sheds at the opposite face of the fabric, the said face-warpthreads are themselves bodi- 1y carried, as-indicated at the line E,from the upper to the lower part of the shed, as will be readilyunderstood.

I claim-- A double-faced fabric in which the face and binder warps arecombined with stuffer or cord Weft and with binder -weft, substantiallyin the manner hereinbefore set forth, whereby a fabric is produced withribs on both of its faces formed by the same face-warps bent about thestuffer or cord weft, the ribs at opposite picks of the fabric beingsubstantially opposite each other, the face-warps being bound down ateach side of each stuffer or cord weft by the binder-warp andbinder-weft, two picks of the latter lying between each two picks of thestuffer or cord weft, the binder-warp separating each two alternatepicks of stnff'er or cord weft, substantially as described.

In testimony whereof I have signed my name to this specificution in thepresence of two subscribing witnesses.

GEORGE CROMPTON.
